CHAPTER ONE: ALGEBRAIC EXPRESSIONS

1.1 Introduction to Algebra

Algebra is a branch of mathematics that uses letters, symbols and numbers to represent unknown quantities. The letters used in algebra are called variables.

Examples of variables include:

Examples of algebraic expressions:

3x + 5
2a² - 4a + 7
(x + 3) / 2

1.2 Terms in Algebra

An algebraic expression is made up of terms. Terms are separated by addition or subtraction signs.

Example:

5x + 3y - 7

The terms are:

5x
3y
-7

Constant

A constant is a number without a variable.

Examples: 5, -8, 10

Coefficient

A coefficient is a number multiplying a variable.

Example:

In 7x, 7 is the coefficient.

Variable

A variable is a symbol representing an unknown value.

1.3 Simplifying Algebraic Expressions

Simplifying means reducing an expression into its simplest form by collecting like terms.

Example:

3x + 5x = 8x

Another example:

4a + 3b + 2a + 5b

Collect similar terms:

4a + 2a + 3b + 5b

Answer:

6a + 8b

1.4 Expansion of Algebraic Expressions

Expansion involves removing brackets by multiplying terms.

Example:

3(x + 4)

Multiply 3 by each term:

3 × x + 3 × 4

Answer:

3x + 12

1.5 Factorization

Factorization is the process of writing an expression as a product of factors.

Example:

6x + 12

Common factor = 6

Answer:

6(x + 2)

CHAPTER TWO: INDICES AND LOGARITHMS

2.1 Introduction to Indices

Indices are powers that show repeated multiplication of numbers.

Example:

2³ = 2 × 2 × 2 = 8

2.2 Laws of Indices

Multiplication Law

When multiplying numbers with the same base, add the powers.

aᵐ × aⁿ = aᵐ⁺ⁿ

Example:

2³ × 2⁴ = 2⁷

Division Law

When dividing numbers with the same base, subtract the powers.

aᵐ ÷ aⁿ = aᵐ⁻ⁿ

Power of a Power

Multiply the powers.

(aᵐ)ⁿ = aᵐⁿ

2.3 Introduction to Logarithms

A logarithm is the inverse operation of indices.

If:

aˣ = b

Then:

logₐ b = x

Example:

2³ = 8

Therefore:

log₂ 8 = 3

Practice Questions

Simplify: 5x + 3x - 2x
Expand: 4(x + 6)
Factorize: 12x + 18
Simplify: 3⁴ × 3²
Find: log₂ 16
